5 Very Good Reasons To Punch A Dolphin In The Mouth ($12), is another one of those wild and wacky books with an evocative title that begs you to discover what is hidden beneath the covers. This is, in fact, a collation of the brilliant scenes that Matthew Inman created for theoatmeal.com. Think hamster with machine guns, kittens wielding samurai swords and a Tryannosaurus in crack who is improving impossible to potty train. The page has had over 100m views and Google estimate that someone Googles a theoatmeal.com creation every 15-30 seconds. This is a book that has been waiting to happen and thank God it finally has.
